Worried a SIM you never bought is registered on your CNIC? Send your 13-digit CNIC number (without dashes) by SMS to 668, or enter it on PTA’s SIM Information System portal at cnic.sims.pk. Both are PTA’s official methods and show how many SIMs are registered on your CNIC, broken down by operator — Jazz, Zong, Telenor and Ufone.
Last verified: November 2026. PTA’s 668 service and the cnic.sims.pk portal were both checked for this guide — the portal was confirmed live on 11 November 2026. Charges and limits can change, so treat the figures below as current at the time of writing.
Quick answer — the two official ways to check
| Method | What to do | What you get back | Cost |
|---|---|---|---|
| SMS to 668 | Text your 13-digit CNIC (no dashes) to 668 | Number of SIMs on your CNIC, per operator | Small standard SMS charge may apply (around Rs 2 plus tax) |
| Online portal | Enter your CNIC at cnic.sims.pk and press Submit | Same per-operator count, on screen | Free |
Neither method shows the actual phone numbers — only how many SIMs each operator has registered on that CNIC. To see the numbers themselves, or to block a SIM you do not recognise, visit the operator’s franchise with your original CNIC.
Method 1: SMS your CNIC to 668
This is the original PTA method, running since 2009, and it works from any Pakistani network with no internet needed.
- Open a new SMS on any phone.
- Type your 13-digit CNIC number with no dashes or spaces — for example, 3520212345671.
- Send it to 668.
- Read the reply. It lists how many SIMs are registered on your CNIC with each operator — Jazz, Zong, Telenor and Ufone.
The reply does not include the phone numbers, only the counts. The SMS carries a small standard charge — PTA’s published material does not state a fixed fee, and recent guides disagree between free and around Rs 2 plus tax, so expect a small charge. Only check your own CNIC: checking someone else’s SIM registration without their consent is an offence under the Prevention of Electronic Crimes Act (PECA), 2016.
Method 2: check online at cnic.sims.pk
PTA’s SIM Information System portal is the free web version of the same check, and it was confirmed loading on 11 November 2026.
- Open cnic.sims.pk in any browser.
- Enter your 13-digit CNIC number with no dashes (the portal shows the example format 6110123456789). Foreign nationals select the Foreign ID tab instead.
- Tick the “I’m not a robot” reCAPTCHA box.
- Press Submit and read the result — the total number of SIMs registered on that CNIC, broken down by operator.
One small caveat: when we checked, the reCAPTCHA widget showed a “quota exceeded” message even though the page loaded — if the captcha will not verify, use the 668 SMS method instead. The portal is free to use. As with the SMS method, it shows counts per operator, not the phone numbers.
How many SIMs can one CNIC hold?
PTA allows a maximum of 5 voice SIMs and 3 data-only SIMs per CNIC — 8 in total, counted across all networks together. If your check shows more SIMs than that, or a SIM on a network you never used, something is wrong and you should act on it right away. PTA has warned that any misuse of a SIM is the sole responsibility of the person it is registered to, so an unknown SIM in your name is your problem to fix, not the operator’s to ignore.
What to do if you find a SIM you do not recognise
- Do not ignore it. A SIM registered to you can be used in your name — and PTA has said the registered owner can be held responsible if it is misused.
- Visit the operator’s franchise or service centre with your original CNIC and ask them to block the SIM. The counts in the 668 reply or portal tell you which operator to visit. Helplines: Jazz 111, Zong 310, Telenor 345, Ufone 333.
- Report misuse to PTA on its helpline 0800-55055 if a SIM in your name has been used without your knowledge.
- Re-check after a few days — send your CNIC to 668 again, or use cnic.sims.pk, and confirm the count has dropped.
If your own SIM is lost or stolen, the blocking steps are different — see our guide on how to block your SIM if your phone is lost or stolen.
What this check cannot do
- It cannot show who owns a mobile number. There is no official way to get a name, CNIC or address from someone else’s phone number. The 668 service and the portal start from your own CNIC only.
- It cannot show the phone numbers. Only the counts per operator. For the numbers, visit the operator’s franchise with your original CNIC.
- It cannot check a number that is not yours. The related PTA code 667 works differently: send the word MNP to 667 from a SIM and the reply reads back that SIM’s own registration details — it only ever answers for the SIM that sends the message.
The portal also offers one more check, printed on the page itself: send N followed by a mobile number (for example, N 03xx3456789) to 76367 for Rs 2 plus tax to find out which network that number belongs to.
Which method should you use?
- No internet, or in a hurry: text your CNIC to 668 — the reply arrives within seconds.
- Want it free and on screen: use cnic.sims.pk — but if the captcha will not verify, fall back to 668.
- Found an unknown SIM: note the operator from the count, then visit that operator’s franchise with your original CNIC to have it blocked, and report misuse to PTA on 0800-55055.
Checking takes under two minutes and costs almost nothing — do it every few months, and always after buying a new SIM, so no SIM sits in your name without you knowing.

FAQs
How do I check how many SIMs are on my CNIC?
Send your 13-digit CNIC number, without dashes, by SMS to 668, or enter it at cnic.sims.pk, PTA’s SIM Information System portal. Either way you get back the number of SIMs registered to that CNIC, broken down by mobile operator — Jazz, Zong, Telenor and Ufone.
Is the 668 SMS check free?
The cnic.sims.pk portal is free. The 668 SMS carries a small standard charge — PTA does not publish a fixed fee, and recent guides disagree between free and around Rs 2 plus tax, so expect a small charge.
How many SIMs can I have on one CNIC?
PTA allows a maximum of 5 voice SIMs and 3 data-only SIMs per CNIC — 8 in total, counted across all networks together. If your check shows more than that, or a SIM you never bought, visit the operator’s franchise with your original CNIC to have it blocked.
Can I see the phone numbers registered on my CNIC?
No. The 668 reply and the cnic.sims.pk portal only show how many SIMs each operator has registered on your CNIC, not the numbers themselves. To see the numbers, or to block a SIM you do not recognise, visit the operator’s franchise with your original CNIC.
